These days, you could stick a camera chip and a 5 watt white LED in 
there and actually WATCH the mixture! Wow, that would be an interesting 
movie...

Hmmm, on second thought that's not entirely insane. You could make a 
generic-ish device that you could place down the carb hole, but run the 
able to through a spare tapped plug, plenty of those on manifolds. Need 
a good frame rate. Though the camera itself would intefere with flow...

I think you nailed it! :-)

Seriously though, it's probably the induction time caused by the long 
stroke, low speed and likely good velocity through the trough. It's not 
a winning design for the present, but it does what it does, very well.

I think the bottom line is, TBI will be good enough for it.

I'll have to ponder on this, all the factors transport time is affected 
by. At least cyl to cyl fuel distribution isn't such a factor.
